Warner eventually led authorities to a pickup truck parked near the family home, in which Ellorah's lifeless body was found.

Warner was charged with murder, assault on a child causing death, aggravated sexual assault of a child, torture, and oral copulation or sexual penetration with a child 10 years or younger, KTLA reported.

Warner was convicted of first-degree murder and received a 50-years-to-life sentence after taking a plea deal, which resulted in his other charges being dropped.

Victoria Law Thomson, Warner's mother, condemned his actions, describing the incident as "a parent's worst nightmare that someone in the human race could behave so inhumanely with no regard."

More than 3 million reports of child abuse involving more than 6 million children are made in the United States every year, according to Childhelp.

The Centers for Disease Control and Prevention data show reports of sexual and physical abuse make up nearly 50 percent of all prevalent adverse childhood experiences.
